3940 5631 d 23 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3913 5635 d 2 h decky /trunk/ mips32: basic SMP support  
3910 5635 d 16 h decky /trunk/kernel/arch/mips32/ eliminate non-standard -D$(MACHINE)  
3908 5635 d 22 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3880 5639 d 20 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3790 5675 d 4 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5675 d 18 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3586 5731 d 4 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3393 5796 d 20 h jermar /trunk/kernel/arch/mips32/src/mm/ Write protection fault should not panic the mips32 kernel if it happens during
copy_to_uspace().		  
3392 5796 d 20 h jermar /trunk/kernel/arch/mips32/src/mm/ cstyle for mips32's tlb.c  
3236 5839 d 20 h decky /trunk/kernel/arch/mips32/src/mm/ limit physical memory to 512 MB (more cannot be used right now, see ticket #29)
fix physical memory detection in gxemul (which doesn't honor uncached flag in TLB)		  
3232 5840 d 3 h decky /trunk/kernel/arch/mips32/src/mm/ fixes  
3231 5840 d 3 h decky /trunk/kernel/arch/mips32/src/mm/ finer granularity (256 KiB)  
3230 5840 d 3 h decky /trunk/kernel/arch/mips32/ fix off-by-one bug
cleanup		  
3228 5840 d 13 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support		  
2745 5991 d 5 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 6012 d 2 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2722 6013 d 2 h decky /trunk/kernel/arch/mips32/ convert ARC specific commands to generic ones  
2720 6013 d 5 h decky /trunk/kernel/arch/mips32/src/mm/ prettyprint tlb command  
2170 6323 d 18 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2071 6396 d 20 h jermar /trunk/ (c) versus (C)  
1888 6521 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6586 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6593 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6594 d 2 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1735 6610 d 6 h decky /kernel/trunk/ make kernel prints case consistent  
1705 6614 d 5 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1702 6615 d 2 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6622 d 9 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1411 6634 d 23 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1396 6637 d 20 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().		  
1288 6654 d 5 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1196 6673 d 3 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1044 6704 d 4 h jermar /kernel/trunk/ Page table locking.  
983 6706 d 1 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
958 6706 d 20 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
836 6734 d 17 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
831 6738 d 0 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).		  
830 6738 d 2 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().		  
815 6740 d 3 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
